Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, which are generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.
In the related art, an enterprise-level network architecture may use load balancing techniques such as HSRP or VRRP, and the above protocol may perform switching of a communication path only when a device fails or is completely unreachable to an upper network.
However, from the discovery that the device fails or the upper network is completely unreachable, not only a certain time is required until the switching of the communication path is completed, but also the network during that time is not available, which in turn affects the normal use of the user. For example, a phenomenon of packet loss occurs.
In view of this, in order to at least partially ameliorate the above-mentioned drawbacks, embodiments of the present application provide a network path adjustment method applied to a server. The server is in communication connection with the access layer switch and the convergence layer switches, and the access layer switch establishes corresponding communication links with the convergence layer switches.
The server monitors the state parameters of the preset types of the convergence layer switch, and when at least one second switch with abnormal state parameters is detected, a switching instruction is sent, so that the access layer switch switches the link to be switched, which is in a working state with the second switch, to other communication links, and the purpose of switching the communication paths in advance before faults occur is achieved.
As embodiments of the present application relate to enterprise-level network architecture, for ease of understanding, an exemplary description of enterprise-level network architecture is provided below. Referring to fig. 1, a schematic diagram of an enterprise-level network architecture according to an embodiment of the present application is provided. As shown in fig. 1, includes a PC, an access layer switch, a convergence layer switch, a gateway. Wherein the PC accesses a backbone network, which may be a telecommunications backbone network or a mobile backbone network, for example, through a gateway. Thus, when a PC needs to access the backbone network, it needs to go through an access layer switch, a convergence layer switch, and a gateway.
The access layer switch in the network architecture is used for directly facing the PC connection of the user and providing the capability of accessing the application system in the local network section, namely, dividing the PC into different virtual local area networks through VLAN (Virtual Local Area Network ) so as to solve the mutual access requirement between adjacent users.
The convergence layer switch is a convergence point of multiple access layer switches capable of handling all traffic from the access layer devices and providing an uplink to the backbone network, thus requiring higher performance and switching speed and fewer interfaces than the access layer switches. The interface between the access layer switch and the convergence layer switch is in a trunk mode, so that the same interface allows different VLANs to pass through.
Referring to fig. 2, a flowchart of a network path adjustment method performed by the server is shown, and each step of the method will be described in detail below. The server is in communication connection with the access layer switch and the convergence layer switches, and the access layer switch and the convergence layer switches are respectively established with corresponding communication links. As shown in fig. 2, the network path adjustment method includes:
in step S101A, a first switch and a second switch are determined from a plurality of convergence layer switches.
Wherein, the state parameters of the preset types of the first switch are not abnormal, and at least one state parameter of the second switch is abnormal. The preset type of status parameters may be, but not limited to, memory usage, motherboard temperature, CPU usage, network usage.
The inventor researches and discovers that when the memory utilization rate, the main board temperature, the CPU utilization rate and the network utilization rate are too high, part of equipment resources are excessively utilized, and part of equipment resources are underutilized, so that equipment faults or transmission faults and the like of a machine with overlarge load pressure occur.
As a possible implementation manner provided in the embodiments of the present application, the server obtains preset types of state parameters of each convergence layer switch, where each type of state parameter is configured with a corresponding threshold.
The server compares state parameters of the convergence layer switch with corresponding thresholds for each convergence layer switch; and determining the first switch and the second switch according to the comparison result of the plurality of convergence layer switches.
Namely, for each convergence layer switch, if one state parameter of the convergence layer switch exceeds a threshold value corresponding to the state parameter, classifying the state parameter into a second switch; otherwise, it is classified to the first switch.
Illustratively, the server may obtain the state parameters of each convergence layer switch through a snmp tool based on the computer language Python.
Step S102A, determining whether there is a link to be switched in the communication link.
The link to be switched is a communication link which is in a working state and is in communication connection with the second switch.
For example, referring again to fig. 1, assume that access layer switch SW3 establishes a communication link with convergence layer switch SW1 and convergence layer switch SW 2. Wherein the communication link between the access layer switch SW3 and the convergence layer switch SW1 allows data of the virtual local area networks VLAN1, VLAN2 to pass through. The virtual local area network VLAN1 includes a PC1, and the virtual local area network VLAN2 includes a PC3.
When the PC1 and the PC3 access the backbone network, communication data is transmitted via the communication link between the access layer switch SW3 and the convergence layer switch SW1, that is, the communication link between the access layer switch SW3 and the convergence layer switch SW1 is in an operating state.
It should be appreciated that the access layer switch SW3 may also be communicatively connected to other convergence layer switches via other communication links, but merely as a redundant backup path, i.e. not in operation.
Referring again to fig. 1, the communication link between the access layer switch SW3 and the convergence layer switch SW2 allows data of the VLAN3 to pass through.
If the CPU utilization of the convergence layer switch SW1 is 93%, and exceeds a threshold of 90%, classifying the convergence layer switch SW1 into a second switch, and taking the communication link between the corresponding access layer switch SW3 and the convergence layer switch SW1 as the link to be switched.
In order to avoid failure of the convergence layer switch SW1 due to excessive load of the CPU, it is necessary to switch data, which is required to be transmitted via the communication link between the access layer switch SW3 and the convergence layer switch SW1, to other communication links before the convergence layer switch SW1 fails.
Namely, after the communication data in the virtual local area network VLAN1 and/or VLAN2 is transmitted through other communication links, the CPU load of the convergence layer switch SW1 can be relieved, and the probability of failure of the convergence layer switch SW1 is reduced.
Step S103A, if yes, a switching instruction is sent to the access layer switch.
The switching instruction comprises an identification of a link to be switched and an identification of a target switch, and the target switch belongs to the first switch.
Also taking the above-mentioned convergence layer switch SW2 as an example, since all the state parameters of the preset categories of the convergence layer switch SW2 are smaller than the corresponding threshold values, the convergence layer switch SW2 is classified as the first switch. Therefore, the data transmitted by the communication link between the access layer switch SW3 and the convergence layer switch SW1 can be switched to the communication link between the access layer switch SW3 and the convergence layer switch SW2, that is, the convergence layer switch SW2 is the target switch.
Therefore, the server may send a handover instruction to the access stratum switch SW3, where the handover instruction may carry the identifier of the link to be handed over and the identifier of the target switch.
After receiving the switching instruction, the access layer switch SW3 sends data to be sent through a communication link between the access layer switch SW3 and the convergence layer switch SW1 through the communication link between the access layer switch SW3 and the convergence layer switch SW2 according to the carried identification of the link to be switched and the identification of the target switch.
Therefore, the server transmits data, which needs to be transmitted through the second switch, in the access layer switch via the communication link with the first switch according to the first switch and the second switch in the convergence layer switch. Because the second switch is a convergence layer switch with at least one abnormal state parameter, the switching of the communication path can be completed before the second switch fails, and the switching time required by equipment failure is reduced.
In the embodiment of the present application, in order to implement path switching with smaller granularity, the server is configured with a preset correspondence between the number of abnormal state parameters and the number of devices. The abnormal state parameter is a state parameter which is abnormal in a second switch which is in communication connection with the link to be switched.
Therefore, the server acquires the number of the abnormal state parameters, and acquires the number of the equipment to be switched according to the preset corresponding relation between the number of the abnormal state parameters and the number of the equipment; and carrying the number of the devices to be switched in the switching instruction and sending the switching instruction to the access layer switch together.
Referring to fig. 1 again, the access layer switch SW3 has 3 PCs, namely PC1, PC2 and PC3, connected to the user terminal. Wherein PC1 is located in VLAN1 and transmits data via a communication link between access layer switch SW3 and convergence layer switch SW1, and PC3 is located in VLAN2 and similarly transmits data via a communication link between access layer switch SW3 and convergence layer switch SW 1.
If the preset correspondence between the number of abnormal state parameters and the number of devices is 1:1, that is, if the convergence layer switch SW1 has 1 state parameter abnormal, transmitting the transmitted data of 1 PC (PC 1 or PC 2) through a communication link between the access layer switch SW3 and the convergence layer switch SW 2; if there are 2 types of state parameters in the convergence layer switch that are abnormal, the data transmitted from 2 PCs (PC 1 and PC 2) are transmitted via the communication link between the access layer switch SW3 and the convergence layer switch SW 2.
Of course, the above corresponding relationship can be adaptively adjusted by a person skilled in the art according to actual needs, and the embodiment of the present application is not specifically limited.
In other words, in the embodiment of the present application, the number of devices that need to adjust paths is determined according to the number of abnormal state parameters of the convergence layer switch, considering that the number of abnormal state parameters of the convergence layer switch is positively correlated with the probability of occurrence of a fault.
Of course, the device may be a PC, a smart phone, a personal computer (Personal Computer, PC), a tablet computer, a personal digital assistant (Personal Digital Assistant, PDA), a mobile internet device (Mobile Internet Device, MID), or the like.
In addition, it is worth noting that each convergence layer switch is configured with a path switching protocol based on network bandwidth. The inventor researches and discovers that the current path switching protocol has unreasonable phenomenon, for example, after the port aggregation protocol performs load balancing configuration, the load balancing configuration is performed only for the interface bandwidth, and the factors such as the memory, the main board temperature, the CPU and the like are not considered, so that the bandwidth utilization rate of part of the switches is not high, but the memory utilization rate is too high. But according to the path switching strategy of the port aggregation protocol, traffic is continuously distributed to the switch with potential faults, so that the probability of the fault of the switch is increased.
In view of this, the embodiment of the present application is based on the path switching protocol of the existing network bandwidth, and the acquired state parameter does not include the network bandwidth parameter. In other words, in the embodiment of the present application, the path switching policy related to the network bandwidth continues to use the existing mature network protocol, and the server switches the communication path only through the state parameters other than the network bandwidth parameters, so as to reduce the probability of the switch failure.
Corresponding to the server, the embodiment of the application also provides a network path adjustment method which is applied to the access layer switch, wherein the access layer switch is in communication connection with the server, and corresponding communication links are respectively established with the aggregation layer switches. Referring to fig. 3, the network path adjustment method includes:

Step S102B, according to the switching instruction, switching the data sent from the link to be switched to the communication link in communication connection with the target switch.
Based on the server and the access layer switch, the embodiment of the application also provides a network path adjusting system, wherein the network path adjusting system comprises the server, the access layer switch and a plurality of convergence layer switches, the server is in communication connection with the access layer switch and the plurality of convergence layer switches, and the access layer switch and the plurality of convergence layer switches are established with corresponding communication links;
